Breathing warm-humid air reduces this phenomenon.Objective: To evaluate EIB prevalence in semi-professional soccer athletes from a tropical humid region.Methods: We included athletes from a soccer team from the city of Recife-Brazil. A history of asthma or respiratory symptoms after exercise, demographic data and baseline FEV1 measurements were obtained. Thereafter, each athlete performed a standardized free field running to achieve 85% to 95% of the maximum calculated heart rate for the last 6 minutes of a total running time of 8 to 10 minutes. FEV1 was measured again at 5, 10, 15 and 30 minutes after exercise and EIB was defined as a reduction ≥ 10% from basal values in two consecutive time points. Results: Fifty-four male athletes aged between 13 and 21 years were evaluated. All denied exercise associated respiratory symptoms. Mean temperature and air humidity were 30.2°C ± 2.7°C and 82.1% ± 2.9%, respectively. EIB was found in two (7%) athletes (with a fall in FEV1 from baseline of 23.3% and 22.6%), none with history of asthma symptoms. Two other athletes had a history of asthma symptoms in childhood but no decrease in FEV1. Conclusion: The studied population of semi-professional soccer athletes with no exercise associated respiratory complaints showed a low BIE prevalence (7%). It may be necessary to perform the challenge with the athlete breathing dry air in those that also play in more dry and cold climates.","PeriodicalId":17085,"journal":{"name":"Journal of Sports Medicine & Doping Studies","volume":"66 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77225310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, we investigate the association between injury incidence rates (IRs), players’ age and playing positions. Methods: Anthropometric characteristics, field-playing positions, match exposure injury occurrences were monitored in 24 teams (432 players). The teams were drawn from four main structures: Premier Soccer League (PSL), first division, super league and regional leagues (promotional league). The type, severity and duration of football-related injuries were documented following FIFA recommendations. Descriptive data was computed to characterize the injury profile using SPSS v23.0. Results: There were no significant differences on age (p=0.234, body mass (p=0.898 and height (p=0.451) among all players. IR of 29.8 (CI: 27.4, 32.2) injuries per 1000 exposure hours were observed. A sum of 92 injuries were observed and recorded. Of these injuries, 3 out of 4 were classified as either minimal (31.5%) or mild (35.9%), while merely 1 out of 10 injuries (5.4%) necessitated absence from play of more than 28 days. Overuse and traumatic injuries accounted for 27.3% and 78.3% respectively. Conclusions: The study reflected that the quantity and severity of injuries were not only associated with player’s age but also different playing positions. The injury profile of this nature can also enhance the knowledge of injuries, identification of risk factors for the most prevalent differential diagnoses in Swaziland soccer. Therefore, assisting sport medical teams and physicians to plan and develop any injury intervention programs.","PeriodicalId":17085,"journal":{"name":"Journal of Sports Medicine & Doping Studies","volume":"24 1","pages":"0-0"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87839974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A BF instrument has three tasks. First is to monitor (in some way) a physiological process of interest. Second is to measure (quantify) what is monitored. Third is to present what is monitored or measured as meaningful information. Electromyography (EMG) and BF are often used simultaneously to handle movement during a procedure. BF is a means for gaining control of bodily processes to increase relaxation, relieve pain and improve health, among other benefits. And BF training (BFT) is not only a technique used for enhancing health, but is predicted to affect the development and maintenance of brain function. One technique for non-invasive measurement of brain activity that has been developed in recent years is brain functional imaging using near-infrared spectroscopy (NIRS). Compared to other techniques of measurement of brain activity, NIRS is a low-restraint and non-invasive measuring technique. In addition, it enables a user to take electrophysiological measurements during activity, such as training or other movements. The connection between BFT and brain function surely will garner further attention in future, as current studies state that BFT involves not only voluntary movement of the extremities and joints, but also receives input from high-level integrative functions of the brain. And furthermore, BFT, which has garnered attention in recent years, has not only revealed the importance of mental training when performing an action, but also monitors subjects’ muscle performance and encourages learning of psychophysiological control. Here, we investigated the connection between BFT and local cerebral blood flow, by performing cranial NIRS with simultaneous electromyogram (EMG), recording from the rectus femoris muscle. Our results suggest that kicking action alters brain function, particularly in a manner that is predicted to activate working memory.","PeriodicalId":17085,"journal":{"name":"Journal of Sports Medicine & Doping Studies","volume":"13 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84593413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: 65 patients aged 13–46 entered our study and were operated with a single bundle ACL reconstruction technique using hamstring tendon autograft. The operation and postoperative protocol were standardized. Patients were evaluated at 3 and 6 months postoperatively with clinical examination, KT–1000 measurements, functional scores (Balance index, Hop index, IKDC, isokinetic testing) and subjective questionnaire (Lysholm score, Tegner score). Results: 65 patients were evaluated 3 and 6 months postoperatively. Lachman test was negative in 92% and the pivot-shift test was negative in 89% of patients at 6 months follow-up. KT–1000 stability testing revealed a difference of 1.05 mm ± 2.83. At final follow-up, overall IKDC evaluation grade A and B were obtained in 96% of patients. The mean Lysholm score, 6 months postoperative was 94. There was no statistically significant difference in the angle of peak torque inflexion at 60°/s at 6 months follow-up. Conclusion: Our study shows that the strength of knee flexion six months after harvesting both hamstring tendons returns. However, there is still a statistically significant difference in knee flexion peak torque, when comparing the operative and non-operative side. Single bundle anatomic ACL reconstruction gives excellent knee stability and good clinical results with normal knee range of motion and returns to the appropriate level of activity.","PeriodicalId":17085,"journal":{"name":"Journal of Sports Medicine & Doping Studies","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87286021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An electrogastrogram examination is a noninvasive method of evaluating gastrointestinal motility and autonomic nervous system activity. However, EGGs are not as widely used in clinical settings as electrocardiograms (ECGs) or electroencephalographs (EEGs) because an EGG can be impacted by electrical activity from the myocardium and the diaphragm (due to respiration), and there is no method to relate the functions of the stomach to the data obtained. This paper examines the effect of exercise on gastric electrical activity using two exercise intensities to confirm the basic biological response of an EGG. It was found that, after high-intensity exercising, the spectrum density at the normal frequency band of the stomach (2.4-3.7 cpm) decreased, which may indicate a decline in gastric activity taking place during exercise. Moreover, after high-intensity exercise, translation error increased significantly. Exercise intensity is thought to affect the electrical activity of not only the gastrointestinal tract, but also of other organs.","PeriodicalId":17085,"journal":{"name":"Journal of Sports Medicine & Doping Studies","volume":"25 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83012067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
